Question

The cost price of 25 articles is equal to the selling price of 20 articles. So gain% is
​

Answer 1

Step-by-step explanation:

the gain percentage is 25%

Answer 2

Cp of 25 = Sp of 20

find: gain%

Let the Cp of one article be rs. 1

Cp of 25 = rs.25

Sp of 20 = rs.20 [as it's given in the question]

Cp of 20 = rs.20 [since we have assumed the cp of 1 to be rs.1]

Gain = sp - cp

Gain = 25 - 20

Gain = rs.5

$gain\% = \frac{gain}{cp} \times 100$

$gain\% = \frac{5}{20} \times 100$

$\frac{500}{20}$

gain% = 25%

Hope it helps

have a great day
